- * Définition de la sidebar (sections + items). Filtrée par SidebarFilter selon les modules actifs.
- * Un item porte une clé `module` quand il appartient à un module activable ; sans clé, il est toujours visible.
+ * Définition de la sidebar (sections + items) — navigation GLOBALE uniquement.
+ * Filtrée par SidebarFilter : `module` (route ajoutée à disabledRoutes si module inactif),
+ * `roles` (section ou item masqué si l'utilisateur n'a aucun des rôles listés ; gate minimal,
+ * le RBAC fin par permission arrive en #1.2).
+ * Les items contextuels (Kanban/Groupes/Archives), feature-flag (Documents, Mail) et user-flag

  * Les labels sont des clés i18n (sidebar.<domaine>.<item>).
